We took our 1984 Honda TRX 200 to the shop and they had it for about 2 weeks before they finally called and said that they had cleaned the carb and changed the battery and that it had started up.

We went and got it and when we got home it would not start so we called them, they said bring it back in, so we did. They called us the next day and said they changed the spark plug, and that it was running. We went and got it again and it ran when we drove it off the truck.

We parked it for about an hour because we were going to get ready to go on a ride. Well, it wouldnt start again.

So we called them and they said the last thing they could do was order a new CDI box and put that on. I decided to just buy it myself, so I didnt have to pay them labor again. We put the new one on today and its still not starting.

Does anyone have any ideas on what we could check to see what in the world is going on with this thing?

So I would first start off by checking for spark. If you don’t know how to do this it’s simple. Take the spark plug out and plug it into the spark plug wire and put the bottom of the spark plug against the engine so it’s touching a good metal part of the head and crank the engine. There should be a good clean blue/orange spark at the plug. If not try the old cdi and repeat. Make sure the run switch is on. If you have spark then great it will be a fuel issue. Try this and get back to us.

posted a while back - it was running at one point - I have all the plastic shroud off - it's down to frame and engine now
-fuel pump: when line from petcock is attached, no fuel comes out other side to carb; the line to the carb is open (can blow through it); I thought when I cranked engine that the pump would spit out fuel on other side but it does not; I removed fuel pump and opened it up - diaphragm looks good - but internal areas had lotsa calcification build up - I cleaned this out and dried it good - the clear plastic pieces (?diaphragms) aren't broken - the spring w/ steel ball on end moves freely; am putting it back on tomorrow; but can anyone answer about the pump? isn't it supposed to pump fuel through it... to other side... to carb? puzzling
-along with fuel pump: I replaced petcock 3 weeks ago (gas tank had rusty fuel in bottom - cleaned it out prior to new petcock); when I turn petcock arrow NOT to on or reserve, fuel comes out of line; when I turn it to on or reserve, fuel doesn't come out; puzzling
-I don't know what's on back of fuel pump - it's a valve that has a hose coming out of it - looks like it goes to engine/carb - I haven't traced this out yet - what is it?
-can squirt gas on air filter and engine will run for 2-3 seconds then stop - fuel in top of carb (under diaphragm) does same
-it likely needs carb rebuild - will get to this - but something isn't allowing fuel to get from fuel pump to carb
-I THINK it has a mikuni model x carb - diaphragm is ID 26mm OD 68mm - hard to find inexpensive diaphragm, I guess because it's a model x
-last thing - I replaced solenoid due to old one clicking; I HAVE to be charging the battery or it won't start/turn over - battery just goes dead; but if charging, it'll turn over nicely; i'm guessing it's a bad battery
-any help appreciated - I've never owned an ATV before - inherited this beast from grandparent in-law

Couple of quick points:
1. the Odyssey, or FL350R. This was 30 years ahead of it's time. Fast as greased owl crap, reliable, stupid fun. Never took off. Fast forward to the RAZR which was just replicating the FL350R. What would Honda have done with it if it took off in '85?
2. Everything about the ATC. Reliable, good power for small displacement, easy to work on, simple front to back, still running 30 years later. My son's 185s is 36 years old and outran a 400 Big Bear the other day until it ran out of gearing and the Big Bear caught it around 50 mph. I can dig a 110 out of the weeds and as long as it has a little compression, I'll make it run in 2 days for about $20. Can't do that with a Yamaha 225.
3, 1981 250R. What happens if you stick a CR250 2 stroke in a trike? Yeah, a death machine. Then by '85 the 250R had a 6 speed and would do 70 from the factory. Death Machine +2. The 250R gave birth to the trike racing circuit.
4. The ATC 70. Small, quiet and reliable. Just never took off. Gave birth to the entire small displacement chinese quad market.
5. 82 200ES - first Big Red. The BR single handedly created the UTV market as we see it today in the Ranger, Mule, etc.
6. The ENTIRE chinese quad market in front of us today came from expired Honda patents from the 80's.
7. 300 fourtrax. By far the most coveted 4x4 in the market right now, absolutely indestructible. Pick one up a couple of years old, stick massive wheels and tires on it, and you have a mud machine. Kinda like the Polaris or Can Am...but reliable. And cheap.
To be fair, Yamaha, Suzuki, Kawa, all picked their game up along the way and make good ATV's. I'll leave the Polaris/CanAm discussion for another day. While Polaris gave birth to the automatic, the reliability issues of both still exist today. While great ATV's, I don't consider them any more than specialty machines.

Somehow I lost all of my spark on my 350Big Bear, its a 1990. It ran well for maybe 3 days! Thought it was the carb. Cleaned it 4 times. It was losing power at midrange. Got worse and worse. Finally nothing!
Are these good coils? I was thinking I could swap?

Im working on a old 1987 honda 125 4 wheeler in the school shop. It will start by getting pulled by another 4 wheeler but wont start with the pull start or Electric Start. When you pull start it it tries to start but when you try the electric start it just turns over but doesnt even act like it wants to start. The spark plug is dry and it shoots fuel out of the back(air filter side) of the carb. Weve had the carb off twice and it is complety clean. What are some things we can try?

I bought a Honda 250sx 1986 but the exhaust is broken. Apparently it's not possible to order a new one. I checked to order one on others compagny but there's noting.
Do you know which exhaust it's possible to install. Is there a company who sold an exaust to fit on my 250sx.
Sorry for my english
Thank you
Marc
